Light, crisp, and golden, this homemade Long John Silver’s-style batter gives you that classic fried fish crunch without a lot of fuss. It’s a simple pantry mix that fries up airy on the outside and stays tender where it counts.

If you’ve ever brought home a basket of fried fish and thought, how do they get it so crunchy?—this is the batter to try next.

It’s thin enough to coat evenly, it puffs and crinkles as it hits the hot oil, and it stays crisp long after you’ve plated it up. That’s the whole point. When you want fried fish that feels like a treat, this batter delivers.

And it’s not just for fish, either. Use it on shrimp, onion rings, chicken strips, even veggies like zucchini. Once you get the hang of the consistency, you’ll start looking for reasons to fry things.

CRISPY AND LIGHT: This batter fries up with a delicate crunch, not a heavy breading.

PANTRY-FRIENDLY: No complicated ingredients. If you bake at all, you probably have most of these on hand already.

RESTAURANT-STYLE TEXTURE: Cornstarch and baking powder help create that airy, crackly coating you’re after.

EASY TO MIX: One bowl. One whisk. No stand mixer, no fancy steps.

I love recipes like this because they don’t ask much from you. Get the oil hot, keep the batter cold, and let the frying do the rest.

WHAT MAKES THIS BATTER TASTE LIKE THE CLASSIC

Copycat batters work best when you focus on texture first. The flavor can be simple, because the crunch is what people remember.

Here’s what’s happening in this one:

Cornstarch helps the coating fry up crisp and light instead of bready.
Baking powder adds tiny bubbles and lift, so the batter puffs a little as it fries.
Cold liquid slows gluten development and helps the batter set quickly in the oil.

A touch of sugar encourages browning and rounds out the salt.

It’s a thin batter. That’s intentional.

A thick batter can taste doughy and it can trap steam, which softens the coating fast. This one coats the fish in a smooth layer, then fries into those craggy, crispy edges you want.

HOMEMADE LONG JOHN SILVER’S BATTER INGREDIENTS

This is the batter mix, plus a short list of what you’ll want on hand if you’re making fried fish the classic way.

You’ll need:

1 cup all-purpose flour
¼ cup cornstarch
1½ teaspoons baking powder
1 teaspoon fine sea salt
1 teaspoon onion powder
½ teaspoon garlic powder
½ teaspoon paprika
1 teaspoon granulated sugar
1¼ cups ice-cold club soda (or ice-cold water)

FOR FRYING FISH (OPTIONAL, BUT HIGHLY RECOMMENDED)

1½ pounds white fish fillets (cod, pollock, haddock, or tilapia), cut into serving-size pieces
½ cup all-purpose flour (for a light pre-dredge)
½ teaspoon salt (for the dredge)
¼ teaspoon black pepper (for the dredge)
Neutral frying oil (canola, vegetable, or peanut oil), enough for 2 to 3 inches in a heavy pot or deep skillet

WHAT IS THE BEST FISH FOR THIS BATTER?

Go with a mild, flaky white fish. You want something that cooks quickly and stays tender.

A few reliable choices:

Cod: thick, flaky, holds up well
Pollock: classic “fried fish” flavor and texture
Haddock: slightly sweeter, still mild
Tilapia: easy to find and budget-friendly

Try to avoid very thin fillets unless you’re watching closely. Thin pieces cook fast, and it’s easy to overdo them before you get that perfect golden color.

THE OIL MATTERS MORE THAN YOU THINK

If your oil isn’t hot enough, the batter absorbs it. That’s when fried fish turns greasy and heavy.

If it’s too hot, the outside browns before the fish cooks through.

A sweet spot for most battered fish is 350°F to 365°F.

A thermometer makes this easier. If you don’t have one, you can still do it—just test a tiny drip of batter. It should sizzle right away and float to the top, bubbling steadily. If it sits there quietly, the oil isn’t ready.

Use a neutral oil with a higher smoke point. Canola and vegetable oil are easy. Peanut oil fries beautifully if you already keep it in your kitchen.

HOW TO MAKE HOMEMADE LONG JOHN SILVER’S BATTER

This is a quick mix, but the details make a difference.

Here is how you make it:

STEP ONE: Mix the dry ingredients

In a medium mixing bowl, whisk together the flour, cornstarch, baking powder, salt, onion powder, garlic powder, paprika, and sugar.

Whisking isn’t optional here. You want everything evenly distributed so the batter fries consistently.

STEP TWO: Add cold club soda

Pour in the ice-cold club soda (or water) and whisk just until you don’t see dry flour.

A few small lumps are fine. Overmixing makes batter tougher.

STEP THREE: Rest the batter briefly

Let the batter sit for 5 minutes while you prep your fish and heat your oil.

It gives the flour time to hydrate and the texture smooths out without extra whisking.

OUR RECIPE DEVELOPER SAYS
If your batter starts to thicken while it sits, whisk in one tablespoon of cold club soda at a time until it flows like heavy cream.

HOW TO FRY FISH WITH THIS BATTER

You can absolutely stop at the batter and use it however you like. But if you want that true fish-and-chips feel at home, this is the method that gives you the best results.

STEP ONE: Heat the oil

Pour oil into a heavy pot or deep skillet until it’s 2 to 3 inches deep.

Heat to 350°F to 365°F.

While the oil heats, line a baking sheet with paper towels or set a wire rack over a baking sheet. A rack keeps the coating crisp because air can circulate under the fish.

STEP TWO: Prep the fish

Pat the fish dry with paper towels.

Moisture is the enemy of crisp batter. A quick pat makes a big difference.

Cut thick fillets into even pieces so everything finishes cooking at the same time.

STEP THREE: Light dredge (don’t skip this)

In a shallow dish, mix ½ cup flour with salt and pepper.

Dredge each piece of fish lightly, shaking off the excess.

This step helps the batter stick. It also prevents bare spots.

STEP FOUR: Batter the fish

Dip the floured fish into the batter.

Let extra drip off for a second or two. You want a coating, not a puddle.

STEP FIVE: Fry in batches

Carefully lower the fish into the hot oil.

Do not crowd the pot. Crowding drops the oil temp fast, and that’s when the coating starts soaking up oil.

Fry for 3 to 5 minutes, depending on thickness, turning once if needed, until golden brown and crisp.

STEP SIX: Drain and keep warm

Transfer fried fish to your rack or paper towel-lined tray.

If you’re frying multiple batches, keep the finished pieces warm in a 200°F oven while you finish the rest. Leave them uncovered so they stay crisp.

HOW TO TELL WHEN THE FISH IS DONE

Battered fish can be tricky because the outside looks perfect before the inside is ready.

A few clues:

The coating is deep golden and feels firm when tapped lightly with tongs.
Bubbling in the oil slows down a little as moisture inside the fish decreases.
The fish flakes easily if you test a thick piece.

If you’re unsure, break open one piece. It should be opaque and flake with gentle pressure.

BATTER CONSISTENCY: THE QUICK CHECK

This batter should pour.

Not watery like milk. Not thick like pancake batter.

A good test: dip a spoon in, lift it out, and watch how it falls. It should run off in a steady ribbon and leave a thin coating behind.

If it’s too thick, add more cold club soda one tablespoon at a time.

If it’s too thin, whisk in one tablespoon of flour at a time.

INGREDIENT SUBSTITUTIONS AND ADDITIONS

Want to tweak it? Easy.

CLUB SODA: Ice-cold water works fine. Club soda adds a little extra lift thanks to carbonation, but you’ll still get great crunch with cold water.

SEASONINGS: Keep it simple, or add your favorites:

¼ teaspoon cayenne for a little heat
½ teaspoon Old Bay-style seasoning for a seafood vibe

A pinch of white pepper for a subtle kick

GLUTEN-FREE OPTION: Use a 1:1 gluten-free all-purpose flour blend. The cornstarch is already doing a lot of crisping work, so this swap tends to behave well. Watch the thickness and adjust with extra cold liquid as needed.

SALT LEVEL: If you’re serving with salty sides or a salty dipping sauce, you can reduce the salt in the batter to ¾ teaspoon.

TROUBLESHOOTING YOUR BATTERED FRIED FISH

If something goes sideways, it’s usually one of these common issues.

The batter slides off the fish

Pat the fish dry first
Do the light flour dredge
Don’t let the batter sit warm near the stove; keep it cool

The coating is pale and soft

Oil temp is too low
You crowded the pot
Batter may be too thick

The fish is greasy

Oil wasn’t hot enough when the fish went in
You flipped too often
Batter sat too long and thickened (then trapped oil)

The coating is dark but fish isn’t cooked

Oil temp is too high
Fish pieces are too thick for the frying time

Lower the heat slightly and fry in smaller pieces

HOW TO SERVE FRIED FISH LIKE A TAKEOUT BASKET

This is the fun part.

Serve your crispy fish with:

French fries or steak fries
Coleslaw
Corn on the cob
Macaroni salad
Simple green salad

And don’t skip a dip.

A quick tartar-style sauce made with mayo, relish, a squeeze of lemon, and a pinch of salt is always a good call. Ketchup works. Ranch works. Hot sauce works. Pick your favorite.

If you’re going for the full fish-and-chips feel, add lemon wedges on the side and sprinkle the fish lightly with salt right after frying. It melts into the coating while it’s still hot.

CAN YOU MAKE THE BATTER AHEAD OF TIME?

Yes, but with a small adjustment.

If you want to prep ahead, mix the dry ingredients and store them in an airtight container. When you’re ready to fry, whisk in the cold club soda right before you start.

Once the liquid goes in, the batter is best used within 30 to 45 minutes.

It will still work after that, but it tends to thicken and lose some of its lift. Easy fix, though—just whisk in a splash of cold club soda to loosen it up.

HOW TO STORE LEFTOVERS

Battered fried fish is best fresh. No surprise there.

But if you have leftovers (and sometimes you do), you can still reheat them and keep a bit of crunch.

IN THE FRIDGE: Store cooled fish in an airtight container in the refrigerator for up to 2 days. If possible, place paper towels in the container to absorb moisture.

REHEATING:

Oven: Reheat on a wire rack over a baking sheet at 400°F for 10 to 12 minutes until hot and crisp.
Air fryer: Heat at 375°F for 6 to 8 minutes, checking once.

Microwave: Not ideal. It warms the fish but softens the coating fast.

IN THE FREEZER: You can freeze fried fish, but the coating won’t be exactly the same. If you do it anyway, freeze pieces in a single layer on a tray first, then transfer to a freezer-safe bag. Reheat from frozen in the oven at 425°F until hot.

FREQUENTLY ASKED QUESTIONS

Can I use this batter for shrimp?
Yes. Shrimp fry quickly, so keep them in the oil only until golden—usually 2 to 3 minutes, depending on size.

Do I need eggs in the batter?
Nope. This style of batter doesn’t rely on eggs. The crisp texture comes from the cornstarch, baking powder, and cold liquid.

Why is my batter not crispy?
Most of the time it’s an oil temperature issue. Keep the oil in that 350°F to 365°F range and fry in small batches.

Can I pan-fry instead of deep-fry?
You can, but it’s harder to get an even crunch. Deep-frying gives the best puff and texture because the batter sets quickly all the way around.

Can I use self-rising flour?
You can, but you’ll need to adjust the baking powder and salt since self-rising flour already contains leavening and salt. It’s easier to stick with all-purpose flour for consistent results.

What’s the best way to keep fried fish crisp for serving?
A wire rack and a low oven. Place fried pieces on a rack and keep them warm at 200°F while you finish frying. Don’t cover them.
